To all eff/0m vit muy concern:

Be it known that l, SAMUEL Bnn'osanrir, a citizen of the United States,residing in liliddletown7 in the county ot Butler and State 'of Ghiqhaveinvented certain new and useful l iprovements in laper-lioxliflalri'nglilachines and the like7 oic which the tolowing is a specilication,reference being had therein to the accompanying drawings.

"lhis invention relates to paper-'box inalting machines. havingparticular relerencc to a new type of semi-automatic machine comprisingfeatures ot construction and operation broadly new in the art to whichthe invention relates.

The main object attained in the invention is a semi-automatic boxmaking` machine oi simple construction]- that can be manufactured inquantities at rela-tively low cost, t*l at will have a wide range oifadaptation for making boites of improved constructioii, of ditlerentstyles and sizes, and which will have a relatively large'productioncapacity on small quantity orders.

llnder present practices in the box manuturing industry, with andwithout the oi: automatic machinery. small quantity orders cannot behandled economically, the time and labor cost of hand-made boxes, andthe job setting operations and details in volved in preparing; thestoel: .tor automatic machinery on small orders being conditions whichpreclude the possibility oi' lov.v cost production.

Small quantity orders for special shapes and sizes ot boxes constitute apercentage oi? the business ot paper box manu i'acti ers and, therefore,an important phase ot the industry. Thus the importance ot' iinproi-'edmachinery which will be eti'ective to increase and cheapen productiomand at the saine time effective also to improve the product structurallywill be appreciated by those informed as to the needs ot the industry.

[it feature oit the invention consists in adapting,`V a new type otgluing' mechanism to semi-automatic box making' machinery whereby toeltect better construction oi' the glued joints as the bores are 'formedon the machine. rllhe improved glue applying mechanism as herein shownand described in modiied form to meet the requirements o ne newmachine.` is substantially7 the same .in j rinciple as that set :forthin my copendinnT application for patent Serial No. 66st,- -l-l filedSept. 24, 1923.

i further Yfeature oli the invention consists in the adaptation ofhigh-pressure mechanism, in conjunction with the glue applyingmcchanisnfi, toetect a iirm adhesion, one

part with another oit the box blanks, at the joints to overcome thefaulty, open-joint construction of boxes made by hand or with unsuitablemachinery.

i feature oi the invention consists in means provided for regulating thejoint rassure mechanism to the thickness ot' the trolre, or the numberof folds oi" the stock .t the joints in order that unit'ormity oi' theapplied processes of production as well as in the quality oit theproduct can be maintained. y

'further feature of the improved ma- A.e consists in means provided formaking body and iid portions ot two-piece boxes, when the saine are ofdifferent sizes to permit ot one telescoping` the other, without making:material changes in the set-up ot' the machine. f

es m ed ll i eration of the machine, as illustrated in theaccompanyingdrawings, described in detail in the 'following'specification and defined and comprehended in the appended claims., ibelieve to be broadly new in the art to which my invention pertains. ltwill be obvious to those skilled in the art that va rions .modificationsand adaptation-s oli the underlying principle of the machine, as hereinset forth, can be made without departing` ii-om the principle of theinvention.

Fig. G is a detail viewillustrating a typeof box adapted to be made onthe improved machine.

The complete machine, as shown in Fig. l, is supported on a hollowcolumn l, which is tapered and externally threaded at its upper end at2. and the end of the column being,l slotted at intervals oit 90o as at3, and

provided with a clamp band 4. A machine head 5 having,- a downwardlyextended p0rtion 6 is `mounted telescopically on column 1, being` heldin fixed relation therewith by means of the clamp band 4. A work table Tis mounted rotatably on portion 6 of the machine head 5 and is adaptedto be adj usted vertically relative thereto by means of an adjustingband 8, threaded onto part 6 as at 9 for a purpose which will p-resentlybe described. Y

rlhe machine head comprises a `power belt wheel or tieht-and-loosepulley 10 mounted ona drive shaft 11 supported in bearing 12, theopposite. end of the shaft being operably connected to a ram 13 by meansof a crank connection 14 of the usual Construction. Ram 13 comprises ahead 15 at its lower portion and an upwardly extended portion 1Gretained in vertical sliding-relation on the machine head by means ofguides 17 fastened on the vertical face of the head by bolts 18, thecrank connection 14 beine made between shaft. 11 and part 16, the samebeing covered by a face plate 19 secured to part 16 by means of screws20.

Also supported on the machine head by means of a bracket 21 and screws22 are compounded levers 23 24, joined one to the other at theiradjoining; ends by a link 25a lever 23 being connected to part 16 of theram 13 as at, 26 and'pivoted in bracket 21 as at 27. Lever 24 is pivotedon the machine head as at 28 and is provided at its lower end with asleeve bearing 29 adapted to sustain operative relation between thelever and a pawl carrying plate, comprisingr a sleeve portion 30 and alaterally extendedr` bifurw cated portion 31, mounted to be actuatedreciprocally, horizontally7 on the downwardly extended portion 6 of themachine head by the lever 24. Plate 30?-31 is provided on theun'der sidethereof with a pawl 32 operatively connected with a ratchet p ear 33which in turn is rigidly secured on the upper `face of the work table 7concentrically of part 6 of the .machine head. By the arrangement of theparts described i-t will be seen that upon each stroke of the ram 13 thework table 7 will be rotated, the extent of rotation as provided in thedescribed construe tion being 90 upon each reciprocation of the ram. c

Also connected to part 13 of the ram mechanism by means of a laterallyextended arm 34 and downwardly ldepending` arms 35, is the gluingmechanism 36, which as here shown comprises the glue container 37, theport closinp, stems 38 with their springpressure devices 39. The detailsof construction of the container and glue applying mechanism being;fully described in mv copending application for -T /etters Patentthereon here in referred to. f Y

No novelty is claimed rcfvlative to the glib ingl mechanism except incombination with other elements of the machine which are coordinatedtherewith in functions of operation of the machine as a whole.

The gluing mechanism and the joint forming;- mechanism-ram lhareactuated reciprocally by means of the crank connection 14 between part16 and shaft 11,-the belt wheel 10 beingr keyed to the shaft in theusual manner of tight-and-loose pulleys and controlled in its idle andoperative relation therewith by a bolt 40 connected to a treadle 41.*lmounted on the base of the machine, by ua link 42. n n 1 The work table7, as herein described, is adapted to be rotated one step-90"* uponeachstroke of ram 13 and the gluingr mechanism 36. The table comprises aplurality-four as here shown-of work supporting; heads 43 adapted tohave a partially folded box positioned thereon by the attendant of themachine.

To retain the boxes in position on the work heads each head is providedon the opposite sides thereof with spring clips 44 which are arranged attheir free ends, which project outwardly, to receive opposite sides ofthe bon edgewise between the springs and the adjacent edges of heads 43,the tension of the springs serving to exertsutiieient pressure on theboxes to hold the firmly in position thereon as the boxes are movedthrough the successive operations of `forining; the glued jointsthereof.

Also associated with the work heads 43 are folding" elements 45 whichserve tofold the en d flaps of the box as the same is moved to posit-ionon the work heads. as shown in Fin'. 5L the bof: being shown in dottedoutlinea the folded endsv then passing under the ouard 46 whichisarransred circumferentially of the machine. and serves to hold "theend of the box in folded relation for the successive operationsof-applying the glue to the end flaps and forminflr the joints as theare acted on bv ram i3.

shown in the detail view of Fig. 3 the direction of rotationof worktable 7 is clock wise the boxes with their sides folded at` richt analesto their bottoms and end flaps extended being put on the work heads 43by the attendant of the machine. the end flaps fr of the box beine;partially folded by hand as the box' is positioned on the work head` thefolds being' completed as the flaps are moved under the folding members45, Upon operC tion of the foot lever 41. the power wheel i0 will bebroufrht into driving;r rela.i tion with shaft l1. and a completereciprocation of the gluing; and ioint formingr mechanisms will takeplace-the work table being rotated a quarter turn on the up or idlestroke of the ram. t

The successive steps of operation of the machine.y as herein shown, areindicated in l Fig. 3 as A, B, C, D. ln the A position the boxes are puton the work supporting heads manually by the attendant. On the firstquarter turn of the work table the same are moved to B position which isan idle position; on the second quarter turn the boxes are moved to Cposition where glue is applied to the end flaps; on the third quarterturn the boxes vare moved to D position where the glued joints areformed under high pressure exerted on the folded ends of the box underthe ram; on the fourth quarter turn of the work table the boxes areagain brought to A position and are reversed end for end by theattendant and replaced on the work heads for the second time around toeffect similar operations on the opposite end of the box. With both endsof the box glued, the same are removed from the work head by theattendant and replaced thereon with another box.

To adapt the work 'supporting heads 48 for gluing both units oftelescopically arranged boxes, work heads 43 are rectangular shaped butnot square., the difference in dimension of length and width beingsufiici'ent to correspond to the difference of width between the top andbottom of the box to permit one to telescope the other. For

theisame reason the work heads are detacln,

ably mounted on the work table and are provided on their under sideswith a pilot 47 and a dowel 48 and' each of the radially ex tended armsthe work table with a pilot hole 49 and two dowel holes 50, one of thedowel holes of each arm being occupied as shown in Fig. 3 by a dowel 4Swhich serves to hold the plate in position on the arm. To adapt the workheads for supporting one or the other of the different units of thebox-top or bottom-the heads are placed on the work table with dowel 4Sin register with one or the other of holes 50 as desired. It will beobvious that work heads of different sizes can be used on the machine,and thus that the machine has a wide range for different size boxes.l/Vhen the heads 43 are changed to positions at right angles to thatshown the folding elements 44 will be retained in the relation shown.

The four work heads with which the machine is provided as herein shownand described merely serve to illustrate the principle of constructionand operation of the machine. A greater or less number can be used asmay be desirable for different styles and sizes of boxes, and othergluing and forming operations and automatic or semiautomatic mechanismscan be provided for on the machine without departing from the p 'incipleand spirit of the invention.

To accommodate the position of guard wire'46 over the box supportinghead. as shown in Fig. 3, a clearance space is provided on the' underside of head l5 of the ram as indicated at 49a in Fig. l. lt will beobvious that the guard wire 46 is not continuous over they worksupporting head in positions A and C and that in each of these positionsthe folding elements 45 and 45 are provided to fold the end flaps, parts45 aoting to fold the opposite side flaps a, which receive the depositof glue thereon, as the boxes are positioned on heads 43, and part tofold the bottom flap over the side flaps after the glue has been appliedthereto, and thus to cause a glued oint to be formed as the box comesunder the pressure of ram 13.

From the foregoingdescription and the accompanying' illustrations of thedrawings the construction and operation of the ma thine as a whole willbe readily understood.
